Abstract: Multiple cutting torches are automatically spaced along a torch bar operating parallel to a main beam spanning a cutting table with an apparatus and method allowing one or all of the cutting torches to be stored completely outside the cutting table when not in use, thereby retaining the entire cutting table width for effective access by the remaining operative cutting torches.

Abstract: A flame cutting machine is provided having a CNC control with a programmable memory wherein the memory is programmed to cause automatic cutting of rows of pieces continuously in succession, and wherein the memory also includes selectively actuatable instructions to prevent the torches disposed at a termination point from automatically proceeding to the next row, but instead to cause the torches to automatically proceed directly to the start-pierce point of the row just completed. The torch or torches which have properly cut a complete piece are turned off, while the remaining torch or torches which have involved a lost cut are re-activated at the start-pierce point so, as the row cutting cycle is repeated, the previously lost portions will now be cut. The memory is also programmed to selectively instruct the machine to reverse from the cut termination point if desired.
